YL-KL26Z实验-4

zhjb1

最近有个项目需操作，我将显示ASCII码和屏幕上显示JSQ:、AD0：~AD7：以及其他固定信息和计数器计数显示的完整程序放上，有时间了，会将ADC程序与此程序结合实现ADC分次测试和取n次平均后的显示。看看此板的ADC的精度如何。当然LCD显示有了，其他的实验数据都可以直接显示出来以便后来的操作。全代码如下[学习可以，转载不可！]：

建议加个副标题

你这个LCD什么型号？有点像电子纸

zhjb1

是10元1个买的没有背光，我把背面的反光层去掉，加了LED背光板，撕的不好，花了，有好的。这个烧了，摔碎了不可惜，实验玩呗。我买的所有的黑白的LCD不超过10元，彩色的TFTLCD在10元~15元左右，OLED在10元左右。就是太累，需要到处找他们的芯片型号以及说明手册，而后在不同的单片机上测试通过。至今还有几类黑白的LCD、彩色的TFTLCD、OLED没有测试出来文字，只是刷屏没有意义。

多谢分享。。。

液晶屏改背光加个柔光板效果要好些，就是不太容易找到。

谢谢分享，学习一下

是的，背光板好找，1~2元1块，但散光板或柔光板无处觅。只好贴了一块半透纸代替的，效果很不好。

不错，谢谢分享。。。各种屏幕驱动
